Cellular Phone EMFs May Disturb Learning

Certain previous studies have suggested that high frequency non-ionizing radiation, such as that emitted by cellular phones, may exert a deleterious effect on the human body as it induces a localized warming of body tissues. Nora Prochnow, from Ruhr-University Bochum (Germany), and colleagues have produced data linking extremely high-powered electromagnetic fields (EMFs) with a negative influence on learning processes on the synaptic level within the brain, independent from other factors.  The team placed rats into differently powered non-thermal high frequency electromagnetic fields (HEFs) in the operating range typical of cellular phone emissions.  Synaptic learning and memory formation were analyzed by electrophysiological methods. Furthermore, all animals were tested for stress hormone release immediately following the HEF exposure. Although there was daily training and effortless contact to the exposure environment, increases in blood derived stress hormone levels could be detected for all exposed groups. The team submits that this stress clearly influences learning and memory formation on the synaptic level in the rat brain. Observing that: “In the animal model, it can be demonstrated that neuronal mechanisms of synaptic learning can serve as a target for high powered EMFs,” the team urges special consideration of EMF exposures be given in special occupational situations, such as during the use of body worn antenna systems  common for security services or military purposes.
